PLANETARY GEAR TRAIN OF AUTOMATIC TRANSMISSION FOR VEHICLES

摘要

A planetary gear train may include an input shaft, an output shaft, first and second planetary gear sets each having three rotation elements, a first rotation shaft directly connected to one rotation element of the first planetary gear set and one rotation element of the second planetary gear set, and selectively connected to the input shaft, a second rotation shaft directly connected to another rotation element of the second planetary gear set and directly connected to the output shaft, a third rotation shaft directly connected to another rotation element of the first planetary gear set and the remaining rotation element of the second planetary gear set, and selectively connected to the input shaft and/or selectively connected to a transmission housing, and a fourth rotation shaft directly connected to the remaining rotation element of the first planetary gear set, and selectively connected to the input shaft through two paths and/or selectively connected to the transmission housing.

1. A planetary gear train of an automatic transmission for a vehicle comprising:
an input shaft receiving torque; an output shaft disposed in parallel with and apart from the input shaft; a first planetary gear set having three rotation elements; a second planetary gear set having three rotation elements; a first rotation shaft directly connected to one rotation element of the first planetary gear set and one rotation element of the second planetary gear set, and selectively connected to the input shaft; a second rotation shaft directly connected to another rotation element of the second planetary gear set and directly connected to the output shaft; a third rotation shaft directly connected to another rotation element of the first planetary gear set and the remaining rotation element of the second planetary gear set, and selectively connected to the input shaft and/or selectively connected to a transmission housing; and a fourth rotation shaft directly connected to the remaining rotation element of the first planetary gear set, and selectively connected to the input shaft through two paths and/or selectively connected to the transmission housing.
